So I think I am going to keep my CPR HOB
refugium but I need a new light for it. I had a small coralife 2x9w CF
fixture, but the plastic ends/lens got all brittle and it is falling apart (crappy quality for something meant to be used on a fish tank) so I set it on my kids 3gal FW
aquarium to keep the elodia and platys happy.
The Fuge is 13" long x 4.5" wide x 11.5" deep. The water is 6.5" from the surface to the fiji mudd bottom. I have some live rock rubble and a wad of Chaetomorpha Algae (that I harvest now and then) in it. I also have my aquachef auto feeder mounted on the end that feeds back to the tank (takes up about 3").
How much light do I need for a small refugium? I like the CPR fixtures but $60 (with acrylic stands) seems way high. I found a 12" LED
"bar" on ebay for $26 delivered. From ebay:
You get a 12-LEDs fully submersible Lighting Bar unit with power supply!
This item is one of MeasureExplorer LED aquarium lighting bar serial products. It holds 12 ultra bright blue (465 - 470nm) LEDs with 12 inch long and 5/8 inch diameter. It can be located under water surface for up to 50 inches deep. Universal switching power adapter comes with the item. The tube generates intensive blue light beam, is ready to use by simply plug in the adapter to any AC outlet in the world, it take only 1.2W.
This item is assembled with wide view angle White LED (daylight white, 5600K) and pure blue (465-470nm) narrow view angle LED alternatively. Color effect of this light bar is light blue, or high temperature white (15K-25K), and also blue light beam pattern is generated in the water.
Any comments if this would be enough for some algae in the fuge?
I also saw a 10" fixture (from Taiwan) with a 18w CF bulb (6500k) for $40 delivered that looks similar to the CPR light. Would that be a better choice? Any suggestions?
(Can I post links to these lights? I am not sure if that is allowed on here.)
